EXAMPLE 4 PREPARATION OF 1-[(5-METHOXY-1,5-DIOXOPENTA)-YL1-4-(S)-PHENYL OXAZOLIDIN-2-ONE (FORMULA III) 300 g of monomethyl glutarate was taken into a four neck round bottom flask containing 1500 ml of dichloromethane under stirring. 684 ml of triethyl amine was added at 20 C. followed by the addition of 306 ml of pivaloyl chloride. The reaction mixture was stirred at room temperature for 3 hours. 267 g of (S)-4-Phenyl-2-oxazolidinone and 17 g of dimethyl aminopyrimidine was added and heated to 45 C. The reaction mass was maintained at 42 to 45 C. for 7 hours. Reaction completion was confirmed by thin layer chromatography. The reaction mass was cooled to room temperature and 1500 ml of water was added to it. The aqueous layer was separated and extracted with 750 ml of dichloromethane in two equal lots. Total organic layer was washed with 750 ml of water in two equal lots. The organic layer was evaporated under vacuum at 63 C. to get an oily compound. 1200 ml of n-heptane was charged to this oily compound and stirred for 60 minutes. Filtered the separated solid and washed with 600 ml of n-heptane. The compound was dried at 30 C. for 8 hours to get 449 g of the title compound as a crystalline solid. (Yield 75%) Purity by HPLC: 93.48%., 99395-88-7
The synthetic route of 99395-88-7 has been constantly updated, and we look forward to future research findings.
